"Holiday Knights" is the premiere episode of The New Batman Adventures. Despite being originally aired in September, this episode contains three Christmas themed vignettes, all completely unrelated to one another. The first story stars Batman in pursuit of Gotham's dames, Poison Ivy and Harley Quinn; the following tale is about Batgirl's confrontation with Clayface; finally we have the Clown Prince of Crime on the loose with Batman and Robin trying to stop him.
